DS18B20數位溫度感測器探頭 – 可程式設計

這是 DS18B20 感測器的客製化 1 線防水版本. 當您需要測量遠處的物體時非常方便, 或在潮濕的條件下. Using the digital temperature sensor DS18B20 from Dallas Semiconductor and the high thermal conductivity sealant potting, the temperature sensor is highly sensitive and has a small temperature delay. 溫度感測器支援 “1-金屬絲” 介面 (1-金屬絲), 測量溫度範圍-55℃~+125℃. In the range of -10℃~+85℃, 準確度為正或負 0.5 攝氏度. The field temperature is directly transmitted in a digital way of “1-金屬絲”, 大大提高了系統的抗干擾能力. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.

外徑6*30mm不銹鋼管UL2547電纜DS18B20數位溫度感測器

DS18B20 temperature sensor -55℃ ~ +125℃ Power supply 3.0V-5.5V

It is suitable for field temperature measurement in harsh environments. DS18B20 digital temperature sensors all have unique numbers, and the temperature acquisition equipment uses the number to identify the corresponding temperature sensor.

The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication.

We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor. We don’t have a detailed tutorial up yet but you can get started by using the Dallas Temperature Control Arduino library which requires also the OneWire Library.
